Writes Jenny in San Diego: “There are four of these identical laminated signs posted at face height around the tiny front lawn of a house in my neighborhood. The lawn actually would look fine if it weren’t for the rude signs.”

Several months ago, Kenney in Sydney moved in with some new housemates. Last week, he happened to park in a different spot in the driveway. (“We had been asked to not park in the garage as it was used as a gym/personal trainer studio.”)

“The next morning,” he says, “I found this ‘anonymous’ note — despite having just talked with the person responsible, without any mention of their concern.” By way of a response, Kenney decided to give the note the red pen treatment.

“To be fair,” says Loren in Ypsilanti, Michigan,“the owner does live on a popular dog-walking street. The trees are also gigantic, so I’m sure they have a ton of leaves to rake in the fall. Still, this seems a little harsh.”

“About five months ago,” writes Catherine in Massachusetts, a new tenant moved in and began a new exercise regime: running back and forth in the building hallways. “His/her gait is rather lumbering and resonates throughout our apartment,” Catherine says. “We were startled at first, but have come to giggle over this frequent disruption. Apparently, one of our neighbors isn’t laughing.”

From there, things began to escalate. “Fortunately,” Catherine says, the ensuing flame war “just goes to show that most of our neighbors have a great sense of humor.”

Writes Jocelyn in London: “Since moving into halls for the first year of university, our hygiene skills have gone downhill, to say the least. Finally, one of our roommates cracked and cleaned up the rotting mess…or so we thought.” Instead, he just found a new “dumping ground.”
